Develop a simple linear regression equation to forecast annual sales. For this? regression, the dependent? variable, Y, is the demand in each year and the independent? variable, X, is the index for the year? (i.e., X = 1 for year? 1, X = 2 for year? 2, and so on until X = 5 for year? 5).The regression is given by the equation Y= __+__X (round to one decimal place)
